Long-range Transport of Particulate Matter in Nordic Countries

This project evaluates the present level of atmospheric particles in the Nordic countries and determine their origin by characterisation of the particle emissions, the chemical composition and size distribution of atmospheric aerosols through the development and validation of a 3D EMEP Eulerian model.




The model development on including the particle dynamics in the 3D EMEP model was based on using the specific modeling technique, MONO32, recently developed by the Finnish group. This approach facilitated the implementation of the rather complicated particle processes into a large model with very limited remaining computing power. To ensure accuracy of the model, it was first tested in a box model arrangement. The model and the testing are described below. Further the present regional model with particle dynamics implemented is described. The present description in the model of the different processes briefly described.
